Allen Manufacturin poration of Illinois Appucatienouly 2, 1938, 'seraiNoizlmss ,6 Claims. (Cl. 299-141) This invention relates to an improvednozzle for' lawn sprinkling,` and morelparticularly to an improved sprayhead for such a nozzle.

"In the prior fan shaped type of nozzle, to which this invention morespecifically applies, various devices have been employed within thehollow'chamber of the nozzle to cause an even or uniform discharge ofthe water from the spray head. Devices heretofore used, however, areexpensive and otherwise objectionable.

It is the object of this invention to provide a fan shaped type nozzlehaving a spray head which will give the desired uniform spray withoutthe disadvantages of complicated variesv or other obstructions such asheretofore considered necessary and which are objectionable as above setforth.

An illustration of an embodiment of this invention is shown in theaccompanying drawing, wherein:

Figure l is a longitudinal cross section of the improved fan shapednozzle,

Figure 2 is a transverse cross section on the line 2 2 of Figure 1, and

Figure 3 is a perspective view of the improved nozzle.

lar form in plan viewas Vclearly indicated in Figure 3. Saiddepressedareais sharply' set olf from the normal plane of said member 2'.by angularly disposed side portionsA or surfaces 'I which extendcompletely around the said depressed area. The centrally locateddepressed area is elongated longitudinally of the spray head and asshown in Figure 1, it overlies the inlet or throat portion 5. Thedepressed area I is preferably of arcuate form,.concentric or parallelwith the curvature of the cap or spray head 2.

Although there are no required exact dimensions, my preferred embodimentillustrates that the longitudinal dimension of the depression I0 isabout two-fifths the total length of the arc of the spray head 2, andthe transverse dimension 1s approximately defined by the walls 4 of thebody I.r The depth of said depression I0 is preferably within the limitsof from one thirty-second to three thirty-seconds of an inch.

The described construction is very simple and f hence easily andinexpensively manufactured. The elimination of additional parts such ashave Referring now to the drawing, in Figure 1 there is shown a hollowfan shaped body IV having an arcuate spray head 2, and an internallythreaded socket or ferrule 3.

The body I may be of any suitable material, either case, molded, orstamped to form the illustrated fan shaped longitudinal section ofFigure 1 and the parallel walls 4 as shown in Figure 2.

The body I has an inlet portion 5 of circular thereto, for example, bymeans of soldering' flanges such as shown at 9 to the underlyingmarginal portions of the body.

The arcuate spray head 2 which caps the outlet end of the body I, ispierced by a plurality of regularly or uniformly spaced apertures 8.

The central portion I Il of the spray head is depressed relative to thenormal plane thereof, the depressed area being preferably ofrectangupreviously been required in VVnozzles of the type hereinreferred to constitutes an important advantage in the describedimprovement since such elimination reduces the cost of both material andlabor required to produce the structure. V

Actual trial of nozzles embodying the above described construction havedemonstrated that it results in a satisfactory sprayrof uniformdistribution and'length, although the explanation for such result is'notnow known to me.

The above described structure is susceptiblel of being changed in somerespects without de-v parting from the spirit of the invention, thescope of which should 'be determined by reference to the followingclaims, the same being construed as broadly as possible, consistent withthe state of the art.

1. A fan shaped hose nozzle having a longitudinally arched spray headhaving a centrally disposed portion of its surface depressed, saiddepressed portion being also arched and of such curvature as to beconcentric or parallel with the normal curvature of the spray head.

2. A fan shaped hosenozzle having an elongated, longitudinally archedbut transversely vfiat spray head, said spray head having a centrallydisposed portion elongated longitudinally of the spray head depressedrelative to the normal plane of the spray head, said depressed portionbeing longitudinally arched so as tobe substantially parallel orconcentric with the normal curvature Y I of the spray head, and theentire periphery of said depressed portion being connected with thesurrounding portion of the spray head by angularly extending portions ofsaid spray head.

3. A fan-shaped hose nozzle having an inlet part and a spray plate, saidspray plate having a centrally disposed portion elongated longitudinallyof the plate and inwardly offset from the normal plane thereof, saidoffset portion and the opposite end portions of the spray plate eachbeing provided with a multiplicity of outlet openings and said offsetpart being disposed opposite to said inlet part.

4. A fan-shaped nozzle having an inlet part and a long but narrow sprayplate opposite to said inlet part and provided with a multiplicity ofoutlet holes, said spray plate comprising a sheet metal member having aportion of its length intermediate its ends inwardly offset from theplanes of the end portions of the plate, said end portions and saidoiset portion being of relatively smooth and continuoussform and eachprovided with a multiplicity of said outlet holes, and said intermediateoiset part being disposed opposite to said inlet part.

5. A fan-shaped nozzle having'an inlet part and a long but narrow sprayplate opposite said inlet part and provided with a multiplicity ofoutlet holes, said spray plate comprising a sheet metal member having aportion of its length intermediate its ends offset toward said inletpart from the planes of the end portions of the platefsaid end portionsand said offset portion being of relatively smooth and continuous formand each provided with a multiplicity of said outlet holes, and saidintermediate oiset part being disposed opposite to said inlet part.

6. A hose nozzle of the class described having an inlet part and a longbut narrow, longitudinally arched spray plate opposite said inlet partand provided withv a multiplicity of outlet holes, said spray platecomprising a sheet metal member having a portion of its lengthintermediate its ends offset from the normal planes of the end portionsof the plate and disposed in a plane which is substantially parallel orconcentric with the normal curvature of said plate, said end portionsand said oset portion each being provided with a multiplicityy of saidoutlet holes,

and said intermediate offset part being disposed opposite said inletpart.
